Premiere CS6 parameters and declarations

Hello.

I'm writing a plugin for Adobe Premiere CS6. I have a couple of questions about parameters (ANIM_ParamAtom).

I know how to add:

     - sliders (ANIM_DT_LONG,ANIM_UI_SLIDER),

     - color parameters (ANIM_DT_COLOR_RGB, ANIM_UI_COLOR_RGB),

     - checkboxes (13, 8 - i really don't why it's 13 and 8... can anyone help me with that?)

Can anyone tell me how to add Point parameter (onscreen controls), PopUp Menu or a group? I read the documentation placed in SDK but I found nothing so far.

Thanks in advanced! Dave
